Bignonia capreolata
Crossvine
Atrosanguinea', 'Tangerine Beauty', 'Jekyll'

Wonderful climbing vine that produces clouds of trumpet flowers in shades ranging from golden yellow to orange and deep red. While this plant is found in the wild as an understory plant, it performs best in full sun where its early summer flowers are frequented by hummingbirds.
